Add a pipeline example on the New Relic StatsD Integration

[sbrnmorales]

While testing the New Relic StatsD Integration, I needed to automate the process. So, I created a pipeline on GitHub Actions that triggered the New Relic StatsD integration every time a test code push occurred to my main branch. To run both the integration and my k6 test concurrently, I had to implement a workaround using a service container on GitHub Actions. I already have an article published about this configuration (in Portuguese). I'd be glad to translate it to English and add it to your documentation.
